我假设您正在尝试转换一个以fheftj作为列名的值表。不过，你需要参考表格。
那接下来我们终于可以像Snowflake那样来访问数据了(直接把content由STRING CAST 为这个复杂的STRUCT是无法成功的,这里用了一个 Spark的专用函数 FROM_JSON)。 SELECTcontent.os,content.priceFROM(SELECTFROM_JSON(content,'struct<app_version:string,city:string,commodityname:string,commoditynumber:bigint,country:stri...
Number of digits allowed to the right of the decimal point. By default, precision is38and scale is0(i.e.NUMBER(38,0)). Note that precision limits the range of values that can be inserted into (or cast to) columns of a given type. For example, the value999fits intoNUMBER(38,0)but...
Note that because this method is not available in the generic IDbConnection interface, you must cast the object as SnowflakeDbConnection before calling the method. For example: CancellationTokenSource cancellationTokenSource = new CancellationTokenSource(); // Close the connection ((SnowflakeDbConnec...

Another new method is .cast(), which is part of Snowpark DataFrames' methods. Snowpark also requires that all text features be uppercase and not have spaces between words before encoding them. Currently, the values of the CUT feature violate this requirement, so we'll fix it with function...
请注意,对于我的应用程序-假设我可以克服这个错误,我需要向函数添加大约10个以上的输入参数和10+输出值,因此单个输出标量函数解决方案将不起作用。join table(tmp_fn(cast(t.dd as float),cast(t.ostrat as f 浏览17提问于2020-06-06得票数 0 回答已采纳...
The VARIANT and OBJECT columns will also be output as JSON strings by default, forcing us to cast these when inserting them into ClickHouse. Importing to ClickHouse Once staged in intermediary object storage, ClickHouse functions such as the s3 table function can be used to insert the data ...
